Antispam Appliances for Your Network
An antispam appliance is essentially an on-premises server in a dedicated box that you install at your location. The appliance is usually a self-contained Linux-based computer running antispam software that is pre-installed on the appliance. This makes the appliance essentially plug-and-play; you just set it up, connect it to your network, turn it on, and configure it using a simple web-based interface.
When the appliance is up and running, it can provide many, if not all, of the features of on-premises antispam software.
Here are some of the main advantages of using an antispam appliance:
Because the appliance includes its own hardware and pre-installed operating system, you don’t have to worry about purchasing hardware separately, installing an operating system, installing software, or any of the other tasks associated with setting up a server.
After it’s set up, an appliance will pretty much take care of itself. You’ll need to check on it once in a while, but appliances are designed to be self-sufficient.
The appliance may provide other security features, such as antivirus and firewall protection. Thus, a single appliance can handle many of your network’s security and protection needs.
Using an antispam appliance is not without its disadvantages:
Eventually, you’ll outgrow the appliance. For example, if the number of users on your network doubles, you may run out of disk space.
If the appliance fails, you may have trouble getting it back up and running. When a normal Windows server fails, you can usually troubleshoot the problem and get the server back up and running. Because of the self-contained nature of an appliance, troubleshooting it can be difficult when it’s nonresponsive.
